Abstract
A methodology for the investigation of the spatial variation of seismic ground motions is presented. The application of the approach to data recorded at the SMART-1 array in Lotung, Taiwan, suggested that the amplitude and phase variability of the seismic motions over extended areas around a common, coherent component are correlated; i.e., increase in the variability of the amplitudes of the motions recorded at each individual station around a common amplitude identified from the consideration of data recorded at a number of array stations implies increase in the variability of the phases at the individual stations around the common phase, and vice versa. The variabilities of amplitudes and phases around the common component appear also to be, qualitatively, associated with physical parameters. Thus, the approach sets bases for the possible physical modeling of spatially variable seismic ground motions.
